Table grouping by passing columns name from anther table
Hi guys
I'm trying to group my product export csv file by a few keys and an aggregatedColumns "Variant SKU". I got errors on the aggregatedColumns column that added. I spent a few hours searching for a solution on the web, and most suggest using Record.Field to get the column data from passing a column name. Please help.
excel file: Product List sample.xlsm
source csv: products_export_1.csv
expected result: expecting result.csv
Problematic code: (in table "Product List Grouped SKUs")
= Table.Group(#"Added Custom", Table.Column(#"Product List Header Group Key", "Key"), {{"Variant SKUs", each Text.Combine(Record.Field(Record.FromTable(#"Product List Header Group Aggregate"), "Aggregate Column"), ", ")}})
Table "Product List Header Group Aggregate":
Table "Product List Header Group Key"
Error:
Error Detail 1: (this error cannot be reproduced in the sample)
Expression.Error: The key didn't match any rows in the table.
Details:
Key=
Title= xxxxx
Body (HTML)=xxxxx
....
..
Error Detail2:
Expression.Error: The field 'Name' of the record wasn't found.
Details:
Column #=Column18
Aggregate Column=Variant SKU
Please help😔
I can't help you with Error #1 since, as you wrote, the sample does not reproduce it.
For Error #2, try this for your #"Grouped Rows" step
#"Grouped Rows" = Table.Group(#"Added Custom", Table.Column(#"Product List Header Group Key", "Key"), { {"Variant SKUs", each Text.Combine(Table.Column(_, #"Product List Header Group Aggregate"[Aggregate Column]{0}),", ")}})Results

I am using power query in excel but not "Power BI Desktop", so what file should I share?

Hi jlauyfc, i do not understand the purpose but I've solved your error:
BTW: you should read about functions before you use them, the issue was with Record.FromTable - for this function you have to specify Name and Value.= Table.Group(#"Added Custom", Table.Column(#"Product List Header Group Key", "Key"), {{"Variant SKUs", each Text.Combine(#"Product List Header Group Aggregate"[Aggregate Column], ",")}})
